Fiber optics are buried deep beneath the ground, so there is a chance that internet connection is available for those people who availed fiber connections. As for physical bitcoins, I don't think it would be that viable since you need to print or create something like fiat, plus transactions won't be recorded on the blockchain too.
I do believe that physical bitcoins will be available in the near future so that more people start making use of this currency as not everyone owns an internet connection and those who own might not be able to access their wallet in an emergency (network failure or pc crash). However, it would be like black money as the transactions wouldn't be recorded and people will keep buying it to avoid paying taxes.
But doing that seems like we're heading to a fiat-like currency too, right? Especially coins are off-blockchain so anyone can produce as many physical bitcoins as they can given that validation is absent with physical bitcoins.
